Brother MFC-4420C Remote Setup Port USB (COM4) Driver

The Brother MFC-4420C Remote Setup Port USB (COM4) driver helps Windows recognize the USB-connected remote setup interface used by compatible Brother software to communicate with your multifunction device. It is intended for users setting up the MFC-4420C, restoring a missing remote setup connection, or troubleshooting an unrecognized device entry in Device Manager.

Key Features

• Remote setup communication: Supports the connection between the device’s USB remote setup interface and compatible Brother configuration software.
• Device recognition: Helps Windows identify the remote setup port rather than leaving it listed as an unknown device.
• Legacy Windows options: Look for a package matching Windows 10, 8.1, 7, Vista, or XP, and verify its compatibility notes before installation.
• Interface-specific support: Addresses the remote setup port; printing and scanning may require additional Brother drivers or a complete software package.

How to Install Brother MFC-4420C Remote Setup Port USB (COM4) Driver

1. Check your Windows configuration. Confirm your Windows version and whether it is 32-bit or 64-bit. When comparing Windows 10/11 options, note that Windows 11 is not included in the listed supported systems; do not assume a Windows 10 package will work.
2. Choose a matching package. Before starting your Brother MFC-4420C Remote Setup Port USB (COM4) driver download for Windows, check the device model, operating system, and package contents. Select the latest version explicitly compatible with your system, and use a trusted free download source.
3. Prepare the USB connection. Close Brother utilities and follow the package instructions about when to connect the device. If prompted to disconnect it, reconnect only when the installer requests it.
4. Install the driver. Extract the downloaded files if necessary, then run the supplied installer. If the package provides only driver files, use Device Manager’s Update driver option and browse to the extracted folder.
5. Verify operation. Restart Windows if requested, check Device Manager for warning icons, and test the connection using compatible Brother remote setup software. The assigned COM number may differ from COM4 on another computer.

Keep the driver updated when a compatible release addresses connection issues or supports changes to your Windows installation. Before an update, review the package notes and retain a working installer when possible. For this older device, compatibility matters more than choosing a newer package intended for a different Brother model.
